This paper studies the expansion of US child support policies from 1977 to 1992 and its consequences for marriage and fertility decisions. I develop a model showing that child support enforces ex ante commitment from men to provide financial support in the event of a child, which (1) increases premarital sex among couples unlikely to marry and (2) reduces the abortion rate by reducing the cost of child-rearing to single moms. Using variation in the rollout relative to the timing of nonmarital pregnancy, I find that child support policies reduced the likelihood of marriage and reduced the abortion rate.

儿童抚养对选择结婚和生育的影响

本文研究了从1977年到1992年美国儿童抚养政策的扩展及其对婚姻和生育决定的影响。我开发了一个模型，该模型表明子女抚养费会强制男人在发生子女事件时提供经济支持，这（1）增加了不太可能结婚的夫妻的婚前性行为，（2）通过降低婚前抚养费降低了堕胎率。为单身母亲抚养孩子。通过使用相对于非婚姻怀孕时间的变化，我发现儿童抚养政策降低了结婚的可能性并降低了堕胎率。
